The incidence of postoperative nausea and vomiting (PONV) remains high, and improving the accuracy of PONV prediction remains challenging. The primary aim of this study is to examine the impact of anxiety scores evaluated using the Hospital Anxiety and Depression Scale (HADS) on the PONV prediction model. We hypothesized that anxiety and depression, quantified using the HADS, could improve the accuracy of the PONV predictive model. This pilot study evaluated 100 patients. The HADS was conducted by a self-evaluation method before thoracoscopic surgery for lung tumors, and the anesthesia method was standardized. The criterion was whether the nurse in charge of the patient who complained of PONV assessed that drug administration was necessary. As the main analysis, the odds ratio of the HADS score for predicting PONV was evaluated using multivariable logistic regression models. Further, the receiver operating characteristic (ROC) curves of the model with the HADS score added to the variables of without-anxiety predictors and the model with the variables of without-anxiety predictors only were compared. The anxiety score was significantly higher in the PONV group than in the no PONV group (P = 0.021). For predictive accuracy, the model that included age, sex, smoking history, history of PONV, and anxiety score had a higher area under the ROC curve than did the model excluding the anxiety score (P = 0.021). In conclusion, the findings indicate that the HADS is worth investigating as a predictor of PONV.
